Abstract:  Hard coatings and cutting fluids are healthy acknowledged to enhance the performance of cutting tools during the various machining operations, such as machining of MMC and high-speed machining etc. Inappropriately, the growth of cutting tool for high-speed machining of hard and  materials which are quite difficult for cutting has  continue problem for excellence and budget of production. The present work studies the performance of multilayer coated ceramic inserts or tools under the varying cutting conditions of EN-353 Steel. The present work studies the performance of multilayer coated ceramic and carbide inserts or tools under the varying cutting conditions of EN- 353 Steel. A comparison between the performance of all the coated inserts has been made using cutting parameters (speed, feed and doc) by using the Surface roughness A L9 orthogonal Array and ANOVA are applied to study the performance of machining parameters. Optimum parameters have been also found for improved Surface roughness during the machining of EN353.

Keywords: Multilayer coated, Ceramic Inserts Cutting conditions, Surface Roughness.
